WINDOW OR DOOR

Description

[0001] The invention relates to a window or a door according to the preamble of claim 1.

[0002] DE 40 16 771 A1 discloses a window or door according to the preamble of claim 1. EP 0 249 683 A1, EP 0 572 988 A1, and FR 2 074 972 A5 each disclose windows or doors with locking bars and latching devices. Locking bar fittings are also described, for example, in DE 10 2013 100 308 A1.

[0003] To limit or prevent the dynamic and, in some cases, self-destructive movement of window sashes, e.g., due to wind, it is desirable that these sashes be locked after slamming shut, even without moving the locking bar fitting on the frame. Further movement of the sash from this locked position should only be initiated by the user.

[0004] The invention aims to solve this problem and to create a window or door designed accordingly.

[0005] The invention solves this problem by the subject matter of independent claim 1. Advantageous embodiments can be found in the dependent claims.

[0006] According to claim 1, a window or a door is created which has a frame made up of several frame profiles and a sash which is arranged thereon so as to be rotatable about a horizontal or vertical axis of rotation and which is composed of several sash profiles, wherein a locking bar fitting with one or more locking bars is further formed on the sash frame, with which first locking elements can be moved into a locking position for engaging behind corresponding locking elements on the frame and back into an open position, wherein a latch catch device is further provided with which the sash can be locked to the frame in a latching position even when the latch bar arrangement is in the open position and the sash is closed after opening, wherein the release of the latch catch device from the latching position by means of the locking bar fitting takes place in such a way thatthat it is moved from an open position to a locked position and then back to the open position.

[0007] This has several advantages. Through automatic activation of the latch catch device, the sash can be easily locked or held in place on the frame when slamming or closing. In this way, after slamming (and also after slowly closing), the sash is locked to the frame by a latch catch device, without the locking bar fitting having to be moved into its locked position. A particularly advantageous feature is that the latch catch device can be easily deactivated - e.g., by moving the handle into the locked position and then back into the open position. Surprisingly, despite the latch catch device, operating the window requires no additional manual intervention, except for the situation usually encountered after the sash has slammed shut, e.g.The movement of the locking bar fitting, which is necessary anyway for locking the sash due to wind, into the locking position and then - immediately or later - when the sash is to be opened, back into the open position.

[0008] It is preferred - due to its structural simplicity - that the latch catch device comprises a locking pin assembly arranged on the at least one movable locking bar(s) of the sash frame, said assembly comprising a locking pin movable by a drive means, preferably spring-loaded, and a latch assembly arranged on the frame, said latch assembly comprising a base and a latching hook section with a latching lug, behind which the spring-loaded locking pin is latched in the latched position. Furthermore, according to a particularly preferred variant, it can initially be provided that the latching hook section is movably arranged on the base and that the base is fixedly attached to one of the frame profiles of the frame, wherein the latching hook section on the base can be moved back and forth between a release position and a latched position. The drive means acting on the locking pin can be a spring.The spring acting on the locking pin can be designed in a variety of ways, such as a coil spring, a disc spring, an elastomer spring, or the like. However, the drive mechanism acting on the locking pin can also be implemented in other ways, such as a motor or a magnetic drive device, or the locking pin could use gravity as the drive mechanism.

[0009] The latch catch device can be installed in outward-opening window sashes that are set into an opening in a building. It can also be installed in inward-opening window sashes that are set into an opening in a building.

[0010] This mobility can then be achieved in various ways. For example, the locking hook section can be pivotably mounted on the base. However, in another variant, it can also be slidably mounted on the base like a slide.

[0011] According to a preferred embodiment, it can further be provided that the locking hook section on the base can be moved into a release position with the aid of the locking pin, and that the locking hook section can be moved back into the locking position by means of a spring acting on it. This is a simple variant for moving the locking hook section back to its original position. However, the return movement could also be achieved in another way, e.g., magnetically or possibly with the aid of gravity as the drive means (in the appropriate installation position) or with another drive means.

[0012] It is structurally simple if the locking pin assembly has a guide housing from which the locking pin protrudes, wherein the locking pin can be repeatedly pushed from this position into the guide housing by a distance S by pressure on its free end.

[0013] There are various options available to implement the required functionality, whereby the latch catch device is released from the locking position by means of the locking bar fitting in such a way that it is moved from an open position to a locking position and then back to the open position.

[0014] Thus, the locking hook section of the latch assembly can have a support surface on which the locking pin rests when locked to the latch assembly, the support surface being designed and arranged such that the locking pin only protrudes from the guide housing by a portion of the distance S. It can then further advantageously be provided that, after the locking bar fitting has been moved into a locking position from the locked state, the locking pin is extended further than on the support surface of the locking hook section, and that the locking pin moves the locking hook section upon a renewed movement of the locking bar fitting from the locking position into the open position, such that the sash can be opened again.

[0015] The invention also provides a simple and uncomplicated method for deactivating the latch catch device of a window or door according to one of the preceding claims, with which method, when the sash is in the closed position and the latch catch device locks the sash to the frame, the latch catch device is released from the latching position by means of the locking bar fitting in such a way that it is moved from an open position into a locking position and then back into the open position.

[0016] A functionally particularly safe and simple variant of this method is characterized in that the locking pin, when latching onto the locking hook section when the sash is shut or closed, comes to rest on a support surface (of the locking hook section), whereby it is not fully extended out of the guide housing and that when the locking bar fitting is moved into its locking position, it is moved sideways down from the support surface so that it extends further out of the guide housing and that when the locking bar fitting is moved back into its opening position, the locking pin is moved against an edge of the support surface and then moves the locking hook section into a release position so that the sash can be opened again.

[0017] The invention is described in more detail below using exemplary embodiments with reference to the drawings. The invention is not limited to these exemplary embodiments, but can also be implemented in other ways, either literally or in other equivalent ways.

[0018] The following description of the figures describes various embodiments. In the following, the term "window" can be replaced by "door."

[0019] Fig. 1 shows a window. The window has a surrounding frame 1. This is composed of several profiles—frame profiles 10—to form a frame shape, in particular a rectangular shape (on a door, the lower of the frame profiles can be designed as a threshold).

[0020] A sash, which is movable relative to the frame 1, is arranged on the frame 1. The sash has a preferably circumferentially closed sash frame 2 and a surface element 3, such as glazing, inserted into the sash frame 2 and received thereby. The surface element 3 extends parallel to or in a plane which is formed by the X and Y axes of the coordinate system in Fig. 1The sash frame 2 is composed of several sash frame profiles 20 to form a frame shape, in particular a rectangular shape.

[0021] The frame profiles 10 and / or the sash frame profiles 20 can be made of any material, for example a plastic or a metal or a composite of such materials.

[0022] The sash can be moved manually from a closed position using a handle (or motor-driven via a drive) into an open position and from there back to a closed position. For this purpose, it is pivotally mounted on the frame 1 by means of one or more pivot fittings. The pivot axis is preferably a vertical axis (relative to the installation position of the window in a building). The pivot fittings can also allow other movements (such as tilting movements around a horizontal pivot axis, not shown). However, this is merely an optional embodiment within the scope of this invention. The term "rotating" therefore also includes "tilting" or "pivoting" around a horizontal axis within the meaning of this document.

[0023] In the closed position, the sash is secured by means of a locking bar fitting 4, which has one or more locking bars 41 (see e.g. Fig. 2c, which shows one of the locking bars in section) and is locked by means of corresponding locking elements, which are formed on the sash frame 2 - on the locking bar(s) 41 - and which are formed on the frame 1. For the basic structure of locking bar fittings, reference is made to DE 10 2013 100 308 A1 as an example.

[0024] The locking elements (not shown) can be designed in various ways, for example as locking pins or locking rollers, which are provided on the one or more locking bars 41, which are arranged on the sash frame 2 so as to be movable relative to it and which are preferably movable by means of the handle or by means of the motor drive, in particular linearly movable along the associated sash frame profiles on which they are arranged. Corner deflections can be provided in corners, which couple the locking bars provided along the sash frame profiles.

[0025] To lock the sash to the frame 1, the one or more locking bars 41 are moved, preferably by turning a handle or another drive, into a position in which the locking elements engage behind corresponding abutments on the frame 1. This position is called the "locking position" of the locking bar fitting. To open the sash, the locking bar fitting 4 or its locking bars 41 are moved accordingly into a second position in which they do not engage behind the abutments. This position is called the open position of the locking bar fitting 4. In this position, the sash can then be opened by rotating it away from the frame 1.

[0026] The above structure has long been well known to those skilled in the art and requires no further explanation. For example, reference is made to DE 10 2013 100 308 A1, which discloses such a structure.

[0027] If the locking bar fitting is in the open position and the sash has been turned into an open position, it may happen that the sash is repeatedly slammed open and shut, e.g., due to strong winds. This is prevented here.

[0028] This is achieved by an automatic latch catch - hereinafter also referred to as latch catch device 5, which holds the sash in the closed position after it has slammed shut, without the locking bar fitting 4 having been or being moved into its locking position.

[0029] The latch catch device 5 has corresponding devices on the casement 2 and on the frame 1. A locking pin assembly 51 of the latch catch device 5 is formed on the casement 2 and a latch assembly 52 of the latch catch device 5 is formed on the frame 1 (see Fig. 2a ) and b).

[0030] In Fig. 2aThe locking bar fitting has been moved into an open position, i.e., the remaining locking elements (not shown here) on the locking bar(s) do not engage behind the abutments provided on the frame. Therefore, the sash can or could be moved into an open position. However, it can also be moved back into a closed position without moving the locking bar fitting and could possibly open and slam shut, for example, during a storm. This is prevented by the latch catch device 5. However, ensuring rain and air tightness is not a mandatory function of the latch catch or latch catch device 5.

[0031] The latch catch device 5 is preferably arranged on the window opposite the handle and the vertical frame and sash profiles 10, 20 in the usual installation position. However, this is not mandatory. It could also be installed on horizontal frame and sash profiles (not shown here). In this case, the locking bars 41 and the locking elements on the sash frame 2 move in the Y direction and counter to the Y direction. During opening and closing, the sash moves virtually parallel to the Z direction at the beginning and towards the end of its movement.

[0032] The locking pin assembly 51 has a guide housing 510. This is fixed to the locking rod 41, so that the movements of the locking pin assembly 51 of the locking rod (here, for example, in the Y direction - perpendicular to the image plane of the Fig. 2a) can or follows. The guide housing 510 can have an (elongated) shape, which allows it to be inserted into the locking bar 41. It can, for example, be latched thereto (not shown in detail here).

[0033] A driven, preferably spring-loaded, locking pin 511 is movably guided on the guide housing 501 perpendicular to the sliding direction of the locking bar (here the Y direction) (here, in the closed position of the sash, i.e., in and against the X direction). It protrudes with one free end from the guide housing 510. A force accumulator, a spring 512, which can be a helical spring, acts on it in the guide housing 510. The locking pin 511 can thus be pushed a short distance into the guide housing 510 and automatically retract into a further extended position by the drive, in particular by the spring 512 acting on it. When the locking pin is described below, such a driven or spring-loaded locking pin is meant.

[0034] According to a preferred embodiment, the locking pin assembly 51 can be inserted into a hole in the locking bar during fitting assembly, like a locking roller. The spring 512 pushes the locking pin 511 outward. It can preferably be pressed completely into the guide housing 510 against the spring. The locking pin assembly 51 moves with the locking bar 41, which can be moved, for example, via the window handle. The guide housing 510 can have a central opening that is closed by a plug 513 after the spring 512 and the locking pin 511 have been inserted. The term "guide housing 510" should not be interpreted too narrowly. It also includes a base element that is not closed but supports and guides the movable, spring-loaded locking pin 511.

[0035] The locking pin 511 is thus spring-loaded and projects from a guide housing 510 by a distance S and can be repeatedly inserted from this position by pressure on its free end into the guide housing 510 by the distance S or a part of the distance S (see e.g. Fig. 3b ).

[0036] The corresponding latch assembly 52 is formed on the frame profile 10, which corresponds parallel to the sash profile 20. It has a latching hook section 521 or a latching hook section part. It can also have a base 522. The latching hook section 521—in the sense of a latching hook section part with multiple functions—is preferably movably arranged on the base 522. The base 522 can be attached to the frame profile 10, for example, by screwing.

[0037] The locking hook section 521 can be arranged on the base 522 in a driven, preferably spring-loaded manner. Thus, a drive, in particular a spring 523, acts on the locking hook section 521 to move it on the base 522 into a first defined position, in particular to move it back

[0038] The locking hook section 521 can, for example, be pivotally arranged on the base 522. Such an embodiment is shown, for example, in the Fig. 2 and 3 . However, the locking hook section 521 can also be arranged displaceably on the base 522. Such an embodiment is shown in the Figures 6 to 8 .

[0039] The locking hook portion 521 can be moved back and forth at least between a locking position and a release position. It can be moved into the release position by the locking pin 511 and back into the locking position by the drive means, in particular the spring 523.

[0040] In the release position, the sash can be opened. In the locked position, however, it is held by the latching mechanism 5 on the frame 1 if the sash has been closed or closed without the handle being turned to "locked."

[0041] It is preferred that the locking hook section 521 is automatically urged or moved into the locking position by the action of the spring 523, which may be a leg spring, for example, when it has left the locking position in which the locking pin 511 can be locked to it.

[0042] The locking hook section 521 can, for example, be arranged on the base 522 so as to be pivotable about a rotation axis perpendicular to the sliding direction Y of the locking bar 41 of the adjacent frame profile 10. However, it can also be arranged displaceably on the frame profile—preferably parallel to the sliding direction of the locking bar 41. The locking hook section 521 comprises the actual locking lug / locking edge 5214 and a support area 5212, on which the locking pin can rest in the locked state. The latter has a lateral edge 5213. The support area 5212 is located above the base. The locking pin 511 can rest on the support area 5212 in the locked position of the latching device. In this case, it is partially extended. However, it can also rest on the base 522 (or possibly another "deeper level"). In this case, it is further extended from the guide housing 510.

[0043] The spring 523 can be designed, for example, as a leg spring. However, the spring 523 can also be designed, for example, as a helical spring or the like.

[0044] The functioning of this arrangement is as follows: The locking lug 5214 of the locking hook section 521 is in a state in which the wing has been opened, already in preparation, so to speak "waiting" in the "locking position" ( Fig. 2a , 2c , 5a ). This means that the locking bar fitting and, if applicable, its handle are in the "open position." However, the locking pin 511 has not yet been locked into place.

[0045] If the sash is now closed in the Z-direction - either by manual closing or, for example, by impact due to wind influence - the locking pin 511 is connected to the sash by the remaining hook 511 ( Fig. 2a) is moved toward the latching lug 5214. The latching lug 5214 can have a ramp 5211, which is designed such that, upon further closing of the sash, the locking pin 511 is pressed further into the guide housing 510 until the free end of the latching lug 5214 is crossed, so that the spring-loaded locking pin 511 can extend further again. In this position, the locking pin 511 is locked "behind" the latching hook section 521 in a latching position of the latching device 5. It rests on a support surface 5212 of the latching hook section 521, whereby it is not fully extended from the guide housing 510 ( Fig. 5b ). The support surface 5212 can have lateral ramps so that the locking pin 511 is additionally secured in position. The starting ramp 5211 can also have a braking effect if necessary.

[0046] The locking pin 511 can rest on the support surface 5212 in the locking position in which it has crossed the free end of the locking hook section 521. The height of this support surface 5212 (see also Fig. 5a ) is such that the locking pin 511 rests on it, but is not yet fully extended from the guide housing 510.

[0047] The locking pin 511 is now in a position where it cannot be released from the locked position simply by moving the sash. Instead, the latching device 5 must be manually released from its locked position. This still corresponds to a handle position of the sash in the open position.

[0048] The latch catch device can be released from its locking position in a simple manner by moving the locking bar fitting 4 into its locking position and from there back into the open position. This is because if the locking bar 41 is moved linearly, here in the +Y direction or -Y direction, the locking pin 511 is moved laterally past the locking lug 5214 and moved down from the support surface 5212, so that the locking between the locking pin 511 and the locking hook section 521 is canceled ( Fig. 5c ).

[0049] This corresponds to the locking fitting 4 being in the locking position. The sash is thus locked to the frame 1. However, this locking is now achieved by the additional locking elements, such as the additional locking pins or locking rollers or the like of the window, which engage behind the corresponding fixed locking elements, such as the abutments on the frame 1. The locking pin 511, however, is in a position next to the locking hook section 521, in which it is not locked to the locking hook section 521 ( Fig. 5c ).

[0050] If the sash is now to be opened again, the locking elements, which engage behind the corresponding abutments on the frame 1, are moved out of this engagement by moving the locking bar 41 or the locking bar fitting into the open position.

[0051] In order for the window or its sash to be opened again, the locking pin 511 must not be moved back into the locking position, in which it engages behind the locking hook section 521. Otherwise, the sash could not be opened.

[0052] To solve this problem, the locking hook section 521 and the locking pin 511 are matched to one another in such a way that the locking pin, which has been further extended after leaving the support surface 5212 after the locking bar fitting 4 has been moved into the locking position, initially strikes the edge 5213 of the locking hook section 521 laterally when the locking bar fitting and thus also the locking bar 4 on which it is located are moved back into the open position, whereby it then moves the locking hook section 521 into a position, here into a release position, which is a pivoting position here. Fig. 5d). Since the locking hook section has now been moved "to the side," the sash can be opened, as the locking lug 5214 is not in the way of the locking pin (here in the Z direction).

[0053] This can be summarized briefly in other words. If the locking pin 511 is moved in the +Y direction or -Y direction when the locking bar 41 is moved, when the locking bar fitting is moved into its locking position, the locking pin 511 is moved laterally downwards from the support surface 5212 so that it can extend further out of the guide housing 510 and, for example, come to rest on the base 522. When this locking bar 41 is moved back, when the locking bar fitting 4 is moved back into its open position, the locking pin 511 moves against an edge 5231 of the support surface 5212 and moves the latching hook section 521 into a release position ( Fig. 5d ) so that the sash can be opened again.

[0054] In this state, the spring 523, in particular the leg spring, which has been tensioned by the movement - in particular pivoting - of the locking hook section 521 can then relax. The spring 523 then moves the locking hook section 521 back into its locking position ( Fig. 5a ), so that the trap catch device 5 is reactivated or returned to the initial position of the Fig. 5a moved back so that it can be used again.

[0055] It can be provided that the locking position is defined by a stop of the spring 523 or the locking hook section 521 on the base 522.

[0056] The movement of the locking hook section 521 into the release position can also be limited by a lateral stop 5221, e.g., on the base 522. Two end stops 5221, 5221 in opposite directions, in particular pivoting directions, can be provided. Furthermore, it can be provided that the locking hook section 521 can be deflected in two directions of rotation starting from the locking position. For this purpose, the spring, here the leg spring 523, can also be designed such that it can rotate the locking hook section 521 back from both end positions at the end stops 5221, 5221 into the then middle locking position. In this way, the latch catch device 5, which can be actuated from two directions, can be used or installed on a window regardless of the direction of movement of the locking rod 4 when locking or opening.

[0057] The departure of the locking pin 511 from the support surface 5212 behind the locking lug 5214 is positively controlled in the above-described embodiment, as well as in other embodiments of the invention. Preferably, the locking lug 5214 already runs toward the stop approximately halfway through the pivoting movement (locking bar stroke) toward the locking position, i.e., for example, after 10 mm. Thus, upon further actuation of the locking bar fitting 4 by the handle toward the locking position (which is reached, for example, after 20 mm), the locking pin 511 must now leave the area of ​​the locking lug 5214, even if it had been pulled along to this point due to friction.

[0058] Alternatively, the functionality described above can also be implemented on a latch catch device 15, which has a slide-like latching hook section 1521 displaceably arranged on the base 1522. On the casement side, for example, the locking pin assembly 51 of the Fig. 3a) to 3c ) on the sash frame profile 20.

[0059] The latch assembly 152 is again arranged on the frame side. Its fixed lower part or base 1522 is screwed to the frame 1 or a frame profile 10. It has a locking hook section 1521 that can be moved on guides in the longitudinal direction of the profile. This section is designed as a linearly movable carriage and in turn contains a locking lug 15214. This carriage is held preferably centrally on the base 1522 by at least one spring 1523, here by two compression springs 1523, but can be moved against the spring force parallel to the direction of movement of the locking bar of the adjacent sash frame profile.

[0060] The latch assembly works as follows: First, the locking bar fitting is in the open position (handle position of the sash: open). This is Fig. 8ashown schematically. The sash has now been opened. If the sash is now moved toward the frame 1 and pressed shut, the locking pin 511 can snap behind the locking lug or behind the locking hook section 1521 of the latch assembly 152. To facilitate this movement, the locking lug or the locking hook section preferably has a ramp 15211, which promotes a compression of the locking pin 511 during the closing movement of the sash ( Fig. 8b ) and, if necessary, slows the movement speed of the sash. The locking pin 511 of the latch catch device 15 is partially but not fully extended and now rests on the support area 15212. The sash is now locked.

[0061] Now the locking bar fitting 4 is moved into the locking position (handle position of the sash: locked / closed). This is Fig. 8cshown schematically. The sash is locked by means of its standard locking elements such as locking rollers and locking pieces. In this position, the locking pin 511 of the latch catch device 15 has been pulled laterally behind the detent 15214 of the latch assembly 152 (e.g., in or against the vertical Y-direction). In this way, it has crossed and thus left the support area 5212 of the latch hook section 1521, which can be provided with additional approach ramps to facilitate this movement. The locking pin 511 of the latch catch device 15 now rests at a lower level or is further extended than on the support area 15212. This can be a lower support of the base or, as here, the slide-like latch hook section 5212 itself.

[0062] Now the locking bar fitting 4 is moved back to the closed position (handle position of the sash: closed). This is Fig. 8cshown schematically. The locking pin assembly 51 moves with the locking bar 41 towards the locking hook section 1521 of the latch assembly 152. However, the locking pin 511 cannot return to the area of ​​the support surface 12512 behind the locking lug 15214 because this does not have any ramps on its outside, but is a vertical edge 15213. The carriage is therefore moved sideways on its guide until the handle is fully opened. When the locking bar fitting 4 is fully moved into the open position, the locking pin 511 is still next to, but not behind, the locking lug 15214. The sash can now be pushed open. The locking pin 511 leaves the carriage-like locking hook section 1521, which then centers itself again thanks to its two compression springs. The locking mechanism is thus reactivated.

[0063] This latch assembly is also preferably designed symmetrically. It can be used regardless of the direction of movement of the locking bar, without the need for right and left parts. The departure of the locking pin 511 from the support area 15212 behind the detent 15214 is also positively controlled here: the slide-like detent hook section 1521 is already at the movement limit stop of the slide after approximately half a handle stroke (locking bar stroke) towards the locked position, i.e., after 10 mm. The locking pin 511 must therefore now leave the support area 15212 behind the detent 15214 upon further operation of the handle towards the locked position (e.g., reached after 20 mm), even if it had pulled the detent hook section 1521 along with it up to this point.

Claims

1. Window or door which has an outer frame (1) comprising a plurality of outer-frame profiles (10) and a casement frame (2) which is arranged thereon so as to be rotatable about a horizontal or vertical axis of rotation and is composed of a plurality of outer-frame profiles (20), wherein a locking-bar fitting (4) having one or more locking bars (41) is also formed on the casement frame, with which first locking elements can be moved into a locking position for engaging behind corresponding locking elements on the outer frame and back into an open position, characterized in that a catch device (5, 15) is also provided, with which the casement can be latched in a latching position on the outer frame (1) even when the locking-bar arrangement (4) is in the open position and the casement is closed after opening, wherein the catch device is designed in such a way that the catch device (5, 15) is released from the latching position by means of the locking-bar fitting in such a way that the latter is moved from an open position into a locked position and then back into the open position.

2. Window or door according to claim 1, characterized in that the catch device (5, 15) has a locking-pin assembly (51) arranged on the at least one movable locking bar(s) of the casement frame with a preferably spring-loaded locking pin (511) movable by a drive means and a latch assembly (52, 152) arranged on the outer frame (1) with a base (522) and with a latching-hook section (521, 1521) with a latching lug (5214, 15214), behind which the locking pin is latched in the latching position.

3. Window or door according to claim 2, characterized in that the latching-hook section (521, 1521) is movably arranged on the base (522, 1522) and in that the base (522, 1522) is immovably fixed to one of the outer-frame profiles (10) of the outer frame (1) and in that the latching-hook section (521, 1521) can be moved back and forth on the base (522, 1522) between a release position and a latching position.

4. Window or door according to claim 3, characterized in that the latching-hook section (521, 1521) is arranged on the base (522, 1522) so as to be pivotably movable.

5. Window or door according to claim 3, characterized in that the latching-hook section (521, 1521) is displaceably arranged on the base (522, 1522).

6. Window or door according to one of the preceding claims 2 to 5, characterized in that the latching-hook section (521, 1521) is movable on the base (522, 1522) into a release position with the aid of the locking pin and in that the latching-hook section can be moved back into the latching position by means of at least one drive means acting on it, in particular at least by means of a spring (523, 1523) acting on it.

7. Window or door according to one of the preceding claims 2 to 6, characterized in that the locking-pin assembly (51) has a guide housing (510) from which the locking pin (511) projects, wherein the locking pin (511) can repeatedly be pushed from this position into the guide housing (510) by a distance S by pressing on its free end.

8. Window or door according to one of the preceding claims 2 to 7, characterized in that the latching-hook section (521) of the latch assembly (52, 152) has a support surface (5212, 15212) on which the locking pin (511) rests in its latched state, i.e. in its latched state on the latch assembly, wherein the support surface (5212, 15212) is designed and arranged such that the locking pin (511) projects from the guide housing (510) only part of the distance S.

9. Window or door according to one of the preceding claims 2 to 8, characterized in that, after the locking-bar fitting has been moved into a locking position, the locking pin (511) is extended further from the latched state than in the latched state in which it rests on the support surface of the latching-hook section (521, 1521) and is latched behind the latching lug, and in that, when the locking-bar fitting is moved again from the locking position into the open position, the locking pin (511) moves the latching-hook section (521, 1521) in such a way that the casement can be opened again.

10. Window or door according to one of the preceding claims 2 to 9, characterized in that the latch assembly is constructed symmetrically in such a way that it can be used independently of the direction of movement of the corresponding locking bar (41) of the casement.

11. Method for deactivating the catch device (5, 15) of a window or door according to one of the preceding claims, with which, when the casement is in the closed position and the catch device (5, 15) locks the casement to the outer frame, the catch device (5, 15) is released from the latched position by means of the locking-bar fitting in such a way that it is moved from an open position into a locked position and then back into the open position.

12. Method according to claim 11 in conjunction with claims 2 and 7, characterized in that it comprises at least the following steps: a. the locking pin (511) is latched onto the latching-hook section (521, 1521) when the casement shuts or is closed and comes to rest on a support surface (5212, 15212) of the latching-hook section, wherein it is not fully extended out of the guide housing (510), b. the locking pin (511) is then moved laterally down from the support surface (5212, 15212) when the locking-bar fitting is moved into its locking position, so that it extends further out of the guide housing (510) and c. the locking pin is then moved against an edge (5213, 15213) of the support surface (15213, 15212) when the locking-bar fitting (4) is moved back into its open position and then moves the latching-hook section (521, 1521) into a release position so that the casement can be opened again.
